  • Patent number: 11285583
    Abstract: Examples provide a method and apparatus for fastener pin removal. A fastener pin removal tool includes a tool body having a workpiece interface surface, a threaded hole and opposing side edges. A fitting is coupled to the end of the threaded screw that is proximate the workpiece interface surface. The fitting includes a keyhole-slot configured to receive the head of a pin. The keyhole-slot defines a set of spaced-apart jaws configured to engage the head of the pin that is received within the keyhole-slot. A rotational end-piece is coupled to the threaded screw and rotates to cause the fitting and the set of spaced-apart jaws to pull the head of the pin received within the keyhole-slot. As the rotational end-piece pulls the pin head, the pin is removed from a workpiece.
